Seattle-Tacoma International Airport's Voluntary Runway Use Agreement

The voluntary Runway Use Letter of Agreement (Runway Use LOA) does not change the way the Federal Aviation Administration (FAA) assigns aircraft to runways. Instead, the Runway Use LOA gives the public a better understanding of how the FAA generally assigns aircraft to each runway in different weather and traffic conditions both on arrival and departure. The FAA, which has sole responsibility for managing the safe and efficient use of the nation’s airspace, can deviate from the runway uses described in the Runway Use LOA for a variety of reasons.
